    Why did you post your MT4 question in the Root / MT5 General section instead of the MQL4 section, (bottom of the Root page?)

    Next time post in the correct place. The moderators will likely move this thread there soon.

 
In future please post in the correct section
I will move this topic to the MQL4 and Metatrader 4 section.

Jean Francois Le Bas:

first of all thanks you Jean Francois 

i just need it to save in file .mq4 and its should work ?

as i try it and didnt work 

 
  1. freecbc3: its should work ? as i try it and didnt work 
    MT4: Learn to code it.
    MT5: Begin learning to code it.
    If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into yours.

  2. freecbc3: i hope some one can code it 
    or pay (Freelance) someone to code it.

We're not going to code it for you.

Checking for a new bar will avoid getting alerts every tick.
